How many parallel connections does NsClient support? #609

Closed snapps91 closed 4 years ago

snapps91 commented 5 years ago

Hello, I am balancing the nrpe control on two Windows nodes, some connections end randomly in timeout, but the nodes are not overloaded.

Is there a maximum number of requests for nsclient? or should I configure the nodes better?

Currently there are about 6000 services.

Thank you. Snapps.

I've generally found that check_nt scales better than both check_nrpe or check_nsc_web; even though it is deprecated :(

You can set number of response threads if you have very large stups, but with correct config you can have thousands of requests per second without ny issues... It will also depend on what your checks are doing.

Let me know if this does not answer your question.
